TLC5924 - Example Code

Other Parts Discussed in Thread: TLC5924

Hi, I'm working with a number of TLC5924 chips, they are in pairs that are cascaded together (as shown in the datasheet page 11), however I'm am not having much success with being able to successfully load on/off values into the register. Do you have any source code examples that show how to do this that I could use as a reference?

Thanks

Hello Kiyoshi-san, Thanks very much for those examples, I managed to figure out my issue, the SPI peripheral on the micro I'm using had not completed the transmission of the data before I was toggling the latch line, once I ensured that had completed the chips started operating as expect.

Again thanks for your help.

Cheers

John
